hi all, I like the above posts and there seems to be a consensus that the upper chest and neck area is an "information center". this is so true and reminds me of the great poker player Texas Doyle "Dolly" Brunson. He says that every man has two things that he cannot hide; his eyes and his neck. The neck can show much and for aikido attacks can show when the opponent inhales(is weakest here),and most vulnerable. and the eyes rarely lie. any mother can tell you that.
